I have a 1"thick piece of Spalted Maple I want to level and resaw. I used my joiner and got all 4 corners to sit level on the table saw then started feeding it through the planer to flatten the top. It seems the rollers in the planer are pressing down the piece so even though the whole face of the board is smooth it is still convex on that side. Sorry if for some of you this seems to be a basic question but I can't figure out how to level it. The boar has great color and figure to it. I don't want to toss it.
